Osama is classified among among The FBI's Ten Most Wanted Fugitives.

However, on the Usama bin Laden page on the FBI website, there is no explicit statement to the effect that he might be wanted in connection to the September 11, 2001 attacks. 
 

He is wanted in relation to the 1998 African Embassy bombings. 

"USAMA BIN LADEN IS WANTED IN CONNECTION WITH THE AUGUST 7, 1998, BOMBINGS OF THE UNITED STATES EMBASSIES IN DAR ES SALAAM, TANZANIA, AND NAIROBI, KENYA. THESE ATTACKS KILLED OVER 200 PEOPLE. IN ADDITION, BIN LADEN IS A SUSPECT IN OTHER TERRORIST ATTACKS THROUGHOUT THE WORLD."
